Migration of sterilisation clips: case report and review.

A case is reported of a sterilisation clip which was discovered, three years after operation, to have migrated to the subcutaneous tissue. A review of current techniques of female sterilisation is given together with a discussion of other relevant accounts of clip migration. It is shown to be a rare event with no reported serious sequelae. There is no conclusive evidence to suggest that one type of clip is more likely to migrate than another.
